Application filed January 3, 1923. Serial No. 610,458.

To aZZ whom it may concern:

. Be it known that I, Dnwrrr C. JOHNSON, a citizenof the United States, residing at National Soldiers Home, in the county of Elizabeth City and State of Virginia, have invented certain new and useful Improvements in Trusses, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in a truss and more particularly to the pad construction and the manner of mounting the same on the belt, the object being to provide a'truss with an adjustable pad which can be adjusted in respect to the belt without shifting the belt in any Way.

Another object of the invention is to provide a novel form of pad construction so that the resilient pad is self-ventilated.

A still further object of the invention is to provide a construction of truss which can be manufactured very cheaply, the parts being so connected together that they can be readily taken apart.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings,

Figure 1 is a perspective view of my improved construction of truss;

gigure 2 is a section through the same; an

Figure 3 is a plan View with the belt attaching means being removed.

In the drawing 1 indicates a belt, 2 a leg strap and 3 a pad carried by the belt. The pad is composed of a ring-like member 4 preferably formed of wood having a perforated plate 5 against which is arranged a sponge rubber 6 over which is arranged a chamois 7 secured in position by a binding strip 8 preferably formed of paper or some analogous material.

Secured to the ring-like member by screw bolts 9 and 10 is atop member formed of a strip of wood 12 conforming in shape to the ring-like member 4 and of a slightly less diameter having top and bottom plates 13 and 14 carried thereby, which are provided with cross-shaped slots registering with a similarly shaped slot formed in the member 12 and through which is adapted to pass a bolt 15 carrying a nut 16 within the chamber 17 formed in the ring-like member 4, said bolt being provided with ahead 18 having a.

clamping flange 19 for the purpose hereinafter described. Y

It will .be seen that by turningthebolt so as to loosen the nut, the bolt can be shifted in the cross-shaped slot for adjusting thepo-sition of the same. The bolt is passed through the belt 2 and the end of the leg strap is placed between the member 4 and the bottom plate 14 and secured by the bolt 9, which holds the bottom plate 14 spaced from the ring-like member 4. The other end of the plate 14 engages a spacing member 20 so that the top member composed of the strip 12 and plates 13 and 14 is held spaced from the member 4 in order to allow air to circulate into and out of the chamber 17, thereby obtaining a self-ventilating pad. 7

The chamber 17 also forms a pocket in which to conceal valuables.

When the pad is in the position shown and it is desired to adjust the same, it is only necessary to turn the head of the bolt 18 so as to loosen the nut and the pad can be shifted into various positions by allowing the bolt to work in the cross-shaped slot without changing the position of the belt in any respect as the bolt passing through the belt in a predetermined position remains the same at all times and the pad is movable on the bolt in its various adjusted positions, it, of course, being understood that the leg strap can be swung on the screw bolt 9 to adjust it in its proper position.

The plate 13 around the cross-shaped slot is provided with projections against which the belt is adapted to be clamped by the clamping flange 19 of the bolt so that when the bolt is loosened, the pad can be shifted up or down or to the right or left and when the bolt is tightened, the pad will be securely clamped in its adjusted position on the belt and it will be seen that in order to adjust the pad it is only necessary to loosen the bolt and the pad can be moved in different directions.

From the foregoing description it will be seen that I have provided a truss which is composed of a belt having a pad carried thereby in such a mannerthat the pad can be adjusted on the belt into various positions and when it is secured in adjusted porated plate by a piece of chamois'so that air will be allowed to circulate through the sponge rubber. What I claim is j V 1. A pad for trusses composed of spaced ring-shaped members of different diameters,

one of said ring shaped members being provided with a perforated plate, a rubber spongearranged over said plate and secured to said member by a chamois covering, the other member being provided with top and bottom plates provided with cross-shaped slots, one ofsaid plaltes being provided with projections and a belt for supporting said pad having a bolt extending therethrough and passing through the cross-shaped slots,

said bolt having a flange for clamping said belt against the projections of said plate.

2. A truss comprising a belt having a bolt extending transversely therethrough pro-' vided With a flange, a pad adjustably mounted on said'bolt composed of spaced ring V shaped members, one of said ring-shaped members being provided With top and bottom plates having cross-shaped slots to receive said bolt. and provided with projections to engage said belt, the other. ring shaped member being spaced from the last mentioned ringshaped member and having- DEWITT o.
